As rumours ramp up about prospective new Lumia 750 and possibly 850 launches during Mobile World Congress in Barcelona next month, it seems that Microsoft will indeed launch a new phone in February.

However, that phone is more-likely to be the lower mid-range Lumia 650. And it will be launched with relatively little fanfare, it is said, on 1 February - several weeks before MWC even starts.

Windows Central, which cites multiple sources for the inside skinny, also claims that the company will have a low-key presence at the mobile-centric trade show in Spain. That will effectively squash any plans to announce higher-end Windows 10 handsets at that time.

In addition, the website claims that the RM-1182 that has been spotted on Chinese certification documents of late is a mystery to its sources. Indeed, it continues to hear that the 650 will be the last Lumia handset before Microsoft turns its attention to a forthcoming Panos flagship phone instead.

The Lumia 650 is unlikely to make many waves if it does release at the beginning of next month. It is a 5-inch, 1280 x 720 device, with a Snapdragon 210 processor and 1GB of RAM.

It's not even 4G, according to recent specs leaks, so is particularly budget. Other specifications include an 8-megapixel rear camera and a 5-megapixel front-facing snapper.
